ERROR: permission denied for relation table

🚨 PostgreSQL Permission Denied for Relation – Error Explained

When running queries in PostgreSQL, you may encounter the error:

ERROR: permission denied for relation table

1. Grant SELECT privilege

GRANT SELECT ON table_name TO username;

GRANT INSERT, UPDATE, DELETE ON table_name TO username;

GRANT ALL PRIVILEGES ON table_name TO username;

4. Change the table owner (if needed)

ALTER TABLE table_name OWNER TO username;

GRANT USAGE ON SCHEMA schema_name TO username;

CREATE ROLE app_users;
GRANT SELECT, INSERT ON table_name TO app_users;
GRANT app_users TO username;

Best Practices for DBAs

• Follow the principle of least privilege – grant only required access.

• Use roles and groups for scalable permission management.

• Regularly audit table permissions with:

  \z table_name
  

• Document all privilege changes for security compliance.
